CH ECK-ROWER ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 231,242, dated August 17, 1880.

Application filed January 6, 1880.

To all whom it may concern:

Be it known that I, J OEL M. SHAoKELFoRD, of Decatur, in the county of Macon and State of Illinois, have invented a new and Improved Check-Bower Attachment, of which the following is a specification.

Figure l is a plan, showing the device. Fig. 2 is a front elevation of the same.

Similar letters of reference indicate corresponding parts.

The object of this invent-ion is to furnish an improved device to be attached to a cornplanter for the purpose of planting or dropping corn at regular intervals.

A beam is fixed rigidly across the front of the corn-planter in front of the boxes, and has secured to it grooved rollers or pulleys for the support and guidance of the working-rope, and fixed centrally upon the beam is a stand ard supporting a grooved drivingwheel, around which the rope makes a turn as the planter is moved along. The rope being fastened at each end to a stake driven in the ground causes the driving-wheel to revolve and operate the improved device.

The invention consists of a plate secured vertically on the face of the standard, and carrying slotted pointed levers, which are operated by a stud on the face of the driving wheel, which levers are connected by an adjustable rod with the drop-bar of the planter, and by the attachments motion is communicated from the driving-wheel to the drop-bar and sliding bar.

In the drawings, A represents the beam to be secured upon the planter. B is the standard, firmly fixed or secured upon the tongue of the planter and the central part of the beam A. From this standard B a spindle or shaft, 1), projects, upon which revolves the grooved driving-wheel 0, around which passes the rope D, that actuates the device.

E E are the small grooved sheaves, fixed in suitable standards 0 0 upon the central portion of the beam A, under which sheaves the rope D passes; and FF are the caster-pulleys over which the rope D passes, said caster-pulleys being swiveled in lugs d d, that are fixed on the ends of the beam A.

Fixed immovably upon the spindle b is the plate G, to each end of which is pivoted a lever, H H respectively, whose outer and free ends are beveled on each edge to a point. The inner end of the lever H is provided with a stud, which plays in a slot made in the inner end of the lever H, so that the inner ends of these levers H H are held movably together, and the motion of each is imparted to the other.

The lever H has several holes, 11, made in its pointed ends, and in one of these holes h is fixed one end of the connecting-rod 1, whose other end connects with the bar K, by which is operated the dropping slide of the planter, the holes h h in the lever H and the holes 6 t' in the bar K respectively affording so many adjusting-points for the said connecting-rod 1, whereby the position of the bar K is determined and the extent of the movement, also, which it shall give to the sliding bar M of the corn boxes or hoppers, which sliding bar M moves back and forth in the slotted lugs 42, which project from the face of the beam A.

As the wheel 0 revolves in the forward movement of the planter the stud m strikes alternately the pointed ends of the levers H H, causing thereby a lateral reciprocating movement of the connecting-rod I and the bar K, which motion is communicated to the sliding bar M of the planter, and thereby the amount of corn dropped in a given time and the amount dropped at each movement of the said drop-bar is regulated.

This machine is very simple and durable, and will work on any planter. It makes a full drop every time and makes rows of equal distances apart, and stretching the rope does not cause the widening of the distance between the rows.

I am aware that levers and pulleys somewhat resembling mine have been used on check-rowers; hence I do not broadly claim them; but I know of no levers that are arranged and operated in the same manner as mine, nor of any check-rowers provided with swiveled caster-pulleys like those herein shown and described, the advantage of which caster pulleys is that they hold the rope along the Wood beam in such a manner that it cannot get out of place when the planter is at work, as they accommodate themselves to the tendency or direction of the rope at whatever an gle it may pull as the rope passes through the hollow shanks of the caster-pulleys.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a check-r0wer, the combination, with the driving-wheel (J, of the plate G, levers II H, studsfand m, substantially as shown and deseribed,for giving motion to the sliding bar.

2. In acheck-rower, in combination with the beam A, standard B, and grooved drivingwheel 0, the stud 1), plate G, pointed levers H H, stud m, connecting-rod I, bar K, and sliding bar M, substantially as herein shown and described.
